Angelonia plant named ‘Ancaswhi’

ABSTRACT

A new and distinct cultivar of  Angelonia  plant named ‘Ancaswhi’ characterized by its upright to trailing plant habit; moderately vigorous growth habit; freely branching habit; early and freely flowering habit; large white-colored flowers; and good garden performance.

Botanical designation: Angelonia angustifolia.

Cultivar denomination: ‘ANCASWHI’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofAngelonia plant, botanically known as Angelonia angustifolia andhereinafter referred to by the name ‘Ancaswhi’.

The new Angelonia plant is a product of a planned breeding programconducted by the Inventor in Dresden, Germany. The objective of thebreeding program is to create new freely-flowering Angelonia plants withattractive flower coloration and long flowering period.

The new Angelonia plant originated from a cross-pollination made by theInventor during the summer of 2014 in Dresden, Germany of two unnamedproprietary selections of Angelonia angustifolia, not patented. The newAngelonia plant was discovered and selected by the Inventor as a singleflowering plant within the progeny of the stated cross-pollination in acontrolled greenhouse environment in Dresden, Germany during the summerof 2015.

Asexual reproduction of the new Angelonia plant by terminal cuttings ina controlled greenhouse environment in Dresden, Germany since the summerof 2015 has shown that the unique features of this new Angelonia plantare stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Angelonia have not been observed under all possiblecombinations of environmental conditions and cultural practices. Thephenotype may vary somewhat with variations in environmental conditionssuch as temperature and light intensity without, however, any variancein genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Ancaswhi’. These characteristics incombination distinguish ‘Ancaswhi’ as a new and distinct Angeloniaplant:

-   -   1. Upright to trailing plant habit.    -   2. Moderately vigorous growth habit.    -   3. Freely branching habit.    -   4. Early and freely flowering habit.    -   5. Large white-colored flowers.    -   6. Good garden performance.

Plants of the new Angelonia differ from plants of the parent selectionsprimarily in plant and flowering habit as plants of the new Angeloniaare more freely branching and freely flowering than plants of the parentselections.

Plants of the new Angelonia can be compared to plants of Angeloniahybrida ‘Lotrawhi’, disclosed in U.S. Plant Pat. No. 26,235. Inside-by-side comparisons, plants of the new Angelonia and ‘Lotrawhi’differ primarily in the following characteristics:

-   -   1. Plants of the new Angelonia are taller and more upright than        plants of ‘Lotrawhi’.    -   2. Plants of the new Angelonia are more vigorous than plants of        ‘Lotrawhi’.    -   3. Plants of the new Angelonia have larger flowers than plants        of ‘Lotrawhi’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearanceof the new Angelonia plant showing the colors as true as it isreasonably possible to obtain in colored reproductions of this type.Colors in the photographs may differ slightly from the color valuescited in the detailed botanical description which accurately describethe colors of the new Angelonia plant.

The photograph on the first sheet comprises a side perspective view of atypical flowering plant of ‘Ancaswhi’ grown in a container.

The photograph on the second sheet is a close-up view of a typicalflowering plant of ‘Ancaswhi’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photograph and the followingobservations, measurements and values were grown during the summer andautumn in 19-cm containers in a glass-covered greenhouse in Dresden,Germany and under cultural practices typical of commercial Angeloniaproduction. During the production of the plants, day temperatures wereat a minimum of 20° C., night temperatures were at a minimum of 16° C.and light levels ranged from 15 kilolux to 100 kilolux. Plants werepinched two times, two and six weeks after planting rooted young plants.Plants were six months old when the description was taken and sevenmonths old when the photograph was taken. In the following description,color references are made to The Royal Horticultural Society ColourChart, 1995 Edition, except where general terms of ordinary dictionarysignificance are used.
